About the Visual
Formed of the mouth, digestive tract and appended glands, it converts ingested food so that it can be assimilated by the organism.
See digestive system in :
Terminal part of the small intestine between the jejunum and cecum.
Middle section of the small intestine between the duodenum and the ileum; the majority of nutrients are absorbed here.
Anterior section of the small intestine; secretions from the liver and pancreas, as well as food partially digested in the stomach, empty into it.
Digestive gland connected to the duodenum; produces secretions and hormones (especially insulin).
Dilated section of the digestive tract; it stores, stirs and mixes food with the gastric juices it secretes before emptying it into the duodenum.
schema of circulation
Muscular membranous channel of the anterior section of the digestive tract; it allows food to reach the stomach.
Muscular membranous channel connecting the nasal cavity to the larynx and the oral cavity to the esophagus; it enables breathing, ingestion of food and speech.
Terminal section of the large intestine preceding the anus.
sphincter muscle of anus
Muscle ensuring the contraction and relaxation of the anus and enabling defecation.
Terminal orifice of the digestive tube controlled by a sphincter enabling ejection of fecal matter.
Fourth segment of the colon; it carries waste to the rectum.
Tubular extension of the cecum; this appendage is occasionally the site of appendicitis, a severe inflammation.
Anterior part of the large intestine; it receives food particles from the ileum.
First segment of the colon; it absorbs water from food residue before it is excreted.
Third segment of the colon; it stores waste before it is eliminated.
Second segment of the colon (middle section of the large intestine). The right colon (the ascending colon plus half the transverse colon) mainly enables absorption of water.
Small reservoir where bile secreted by the liver gathers before emptying into the duodenum during digestion. Bile helps in the digestion of fatty substances.
Viscera secreting substances, including bile, that help digestion and break up certain toxins contained in the blood.
schema of circulation
Each of the three pairs of organs secreting a liquid (saliva) that contains a digestive enzyme; it is used to moisten food to facilitate its ingestion.
Flexible muscular structure of the oral cavity; it helps in tasting, masticating and ingesting food, and also facilitates speech.
dorsum of tongue
Anterior cavity of the digestive tract enabling ingestion of food; it also aids in breathing.
Narrow section of the digestive tract, about 6.5 meters long, between the stomach and cecum, where a part of digestion and food absorption occurs.
Last wide section of the digestive tract, about 1.5 meters long, where the final stage of digestion and elimination of waste occurs; it includes the colon and the rectum.
